Abstract

Distorted-wave methods are used to remove the effects of one- and two-pion exchange up to order Q3 from the empirical 1P1 phase shift. The one divergence that arises can be renormalized using an order-Q2 counterterm which is provided by the (Weinberg) power counting appropriate to the effective field theory for this channel. The residual interaction is used to estimate the scale of the underlying physics. © 2011 The American Physical Society.
